06 LSJ TVS tuning

[10_penn]

on a cold start, the car idles just fine, and during driving, it runs perfectly fine and idles fine at stoplights. however, right after logging and loading up a new tune, the car runs like shit. wideband is showing it real lean (16.5-18+) and it has significant idle surge. after you start driving again, it runs fine. it is ONLY when restarting a warm engine after loading up a change in a tune.

 

also... if i do a long 3rd gear pull, say from 2k rpms and up, it will knock like crazy, starting about 3k rpms and having a domino effect the rest of the way through the pull. BUT, if i do a 2-3 gear pull, it won't knock at all. any ideas?

 

btw... car is as follows :

 

06 ION Redline

TVS w/3.1" pulley

K&N CAI

LS4 TB

79 lb/hr lucas injectors

GMPP dual pass intercooler endplate/opt B/secondary heat exchanger

diamond 9.5:1 pistons

cometic headgasket/arp headstuds

stock exhaust manifold/2.5" cat-less downpipe/stock cat-back

 

car is being tuned through hp tuners by myself. if you have hpt and want to see logs/tune then pm me

Sounds like something to do with LTFT's

 

I need to see a scan of the car.

 

 

E-mail me a copy of the tune and I will have a look at it.

 

I have done a number of LSJ tunes with good results.
